Abstract (en)
[origin: EP2390570A2] Different types of apparatus (10, 50) for fabricating a deposit (12, 86), method of deposition and an article (80) are presented. The apparatus (10) include a thermal spray gun (16) comprising a combustion chamber (22), combustion zone (28), an air injection port (18), a fuel injection port (20), a nozzle (30) and a liquid injection port (34). The combustion zone (28) exists between the inlet side (24) and outlet side (26) of the combustion chamber (22). The method includes, among other things, providing a fuel and an oxidizer inside the combustion zone (28), initiating combustion inside the combustion zone (28), and directing products of the combustion toward the outlet side (26) to create a combustion product stream. The method also includes introducing a feedstock mixture comprising a feedstock material and a liquid into the combustion product stream to create an entrained feedstock stream, and expelling the entrained feedstock stream from the spray gun through a nozzle to form a deposit on a surface of the article.
